Not sure i know what a UTXO, or at least the acronym ... so can you explain?
Scenario I'm thinking is : buying sats (btc) from a person in a face-to-face transaction. Seller has btc in a central exchange, buyer has non-kyc , self-custodial btc wallet. Would it make sense to transfer the sats through LN, and then convert to BTC chain at a later date ?
